Ab initio Simulations of a Supernova Driven Galactic Dynamo in an Isolated Disk Galaxy
Iryna Butsky, Jonathan Zrake, Ji-hoon Kim +2
We study the magnetic field evolution of an isolated spiral galaxy, using isolated Milky Way-mass galaxy formation simulations and a novel prescription for magnetohydrodynamic (MHD…
The AGORA High-Resolution Galaxy Simulations Comparison Project. II: Isolated Disk Test
Ji-hoon Kim, Oscar Agertz, Romain Teyssier +40
Using an isolated Milky Way-mass galaxy simulation, we compare results from 9 state-of-the-art gravito-hydrodynamics codes widely used in the numerical community. We utilize the in…
Reconciling dwarf galaxies with LCDM cosmology: Simulating a realistic population of satellites around a Milky Way-mass galaxy
Andrew R. Wetzel, Philip F. Hopkins, Ji-hoon Kim +3
Low-mass "dwarf" galaxies represent the most significant challenges to the cold dark matter (CDM) model of cosmological structure formation. Because these faint galaxies are (best)…
